College years are the time when many people establish financial habits that will carry them for the rest of their lives.

About 36% of men and 30% of women between the ages of 18 and 34 live with their parents, according to the U.S. Census Bureau. While many adult children return home for a short period after college while they look for work, others come back for a variety of reasons—and often for longer stays.

About 25% of adults in their 40s and 50s belong to the sandwich generation—the population of middle-aged adults who are taking care of their children and at the same time providing some level of care or support to their elderly parents.
